The specialized atrioventricular (A-V) conduction system was electrophysiologically delineated during open-heart surgery in four patients with congenitally corrected transposition of the great vessels and associated ventricular septal defect and one patient with single ventricle. Two consistent observations were made: 1) In no case was the specialized A-V conduction system found in the right at...

A newborn with an unusual form of truncus arteriosus is described, whose clinical presentation and certain features of her anatomy were more typical of pulmonary atresia with a ventricular septal defect. The morphological differentiation of certain types of truncus arteriosus and pulmonary atresia with ventricular septal defect remains an area of speculation among cardiac pathologists, and rese...

background: given the dearth of data in the existing literature on the size and morphologic variability of secundum-type atrial-septal defect (asd-ii) in adult patients, we aimed to address this issue in a series of consecutive adult patients evaluated by transesophageal echocardiography (tee). methods: a total of 50 patients (68.0% female) with isolated asd-ii underwent tee for the evaluation ...

A review of 55 specimens with congenital heart disease from subjects with Down's syndrome (Mongolism) showed a variety of malformations. For each case a major anomaly was identified and, when present, additional anomalies were recorded. The three leading types of major anomalies, in order of decreasing frequency, were (1) persistent common atrioventricular canal (60%), isolated ventricular sept...

Atrial septal defect (ASD) is a congenital heart defect that is being increasingly treated using percutaneous interventions. However, these techniques are not devoid of complications. One such complication is device embolization. Removal of such closure device poses tremendous risk and consequent complications both by percutaneous retrieval and surgical removal. Herein, we present two cases of ...

IFE expectancy and the degree of invalidism have been considered a function of the type of cardiac malformation in patients with congenital heart disease. When the abnormality involves a large communication between the ventricles or great vessels, however, the pulmonary vascular bed plays an important role in governing prognosis. The following group of congenital malformations are involved in t...

OBJECTIVE The objective of our study was to determine the feasibility of early extubation and to identify the risk factors for delayed extubation in pediatric patients operated for ventricular septal defect closure. METHODS A prospective, observational study was carried out at our Institute. This study involved consecutive 135 patients undergoing ventricular septal defect closure. Patients we...

INTRODUCTION AND OBJECTIVES Aortopulmonary septal defect is an uncommon congenital cardiac anomaly. To date, approximately 300 cases have been reported. We present our experience, emphasizing the importance of early correction to avoid irreversible pulmonary hypertension. PATIENTS AND METHOD Between 1979 and 2000, seven patients underwent surgical repair of this heart defect in our hospital. ...

OBJECTIVES The aim of this study was to analyze the risk factors and mid-term outcomes associated with post-procedure heart blocks (PPHBs) after transcatheter closure of perimembranous ventricular septal defect (pmVSD). BACKGROUND The development of heart blocks remains a major challenge for transcatheter closure of pmVSD. METHODS Transcatheter closure of pmVSD was carried out in 228 patien...
